An innovative high-grade magnetite concentrates production technology has been developed and pilot tested for ferruginous quartzites of the Kursk Magnetic Anomaly. This paper assesses the possibility of using magnetic-gravity separation to obtain high-grade products, suitable for direct metallization, from finely disseminated ferruginous quartzites of the KMA. The results of pilot tests are presented for the current production of high-grade magnetite concentrates from commercial concentrates and for the production of pellets at the Stoilensky GOK, which may be used to draw the following conclusions. Commercial magnetite concentrate may be processed by magnetic-gravity separation. The grade improvement (mass fraction of Fetot) in the pilot tests averaged 1.23 %, while the expected grade increase for industrial MG separation is 1.17 %. Magnetite concentrate for pellet production may also be processed by MG separation. The grade improvement in the pilot tests averaged 1.26 %, while the expected grade increase for industrial MG separation is 1.20 %. Magnetite concentrates are diluted with classes of over 0.045 mm. It is recommended to conduct the tests using classified feed. The processing of MG separation overflows, ground to d80 0.045 mm (the size of stage III industrial grinding), demonstrated the lack of prospects for obtaining any commercial product from this product.
